Advances in Cytogenetics of Fish

Dear Colleagues,

With more than 65,000 species and subspecies occupying a range of biological niches and exhibiting high karyotype diversity, fishes are the most diverse group of vertebrates, making exceptional models for cytogenetic research. To comprehend chromosomal structure and number variation among species, fish cytogenetics first relied on traditional methods like karyotyping and banding techniques (particularly C-banding and Ag-NOR). Because costs have decreased, there has been a notable expansion of fish cytogenetic studies in recent decades. Fluorescence in situ hybridization (FISH) and its derivative techniques, such as whole-chromosome painting (WCP) and comparative genomic hybridization (CGH), are now frequently used in comparative studies and to map different classes of repetitive DNA, including ribosomal DNA, satellites and microsatellites, and transposable elements. Deeper understandings of chromosomal rearrangements, speciation, sex chromosome evolution, karyotype composition (A and B elements), and genome organization have been made possible by these developments. From evolutionary studies to aquaculture and conservation applications to the use of cytogenomics markers to characterize biodiversity, the papers in this Special Issue showcase the range of fish cytogenetic studies. Together, they highlight how crucial it is to combine traditional and contemporary methods to decipher the complexity of fish genomes and support the idea that cytogenetics still plays a crucial role in the knowledge of the evolution of vertebrate genomes.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fishes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
